  Synthesis of α,α′-trans-Oxepanes through an Organocatalytic Oxa-conjugate Addition Reaction

  摘要：

  Oxepanes are found in a wide range of natural products; however, they are challenging synthetic targets due to enthalpic and entropic barriers. Organocatalytic oxa-conjugate addition reactions promoted by the gem-disubstituent (Thorpe-Ingold) effect stereoselectively provided alpha,alpha'-trans-oxepanes. In addition, the potential of an organocatalytic tandem oxa-conjugate addition/alpha-oxidation was demonstrated in a rapid generation of molecular complexity. These organocatalytic oxa-conjugate addition reactions would provide powerful tools for the synthesis of natural products that contain highly functionalized oxepanes.

  double hydroalkoxylation of internal alkynes could be achieved using a Grubbs-type ruthenium carbene complex or its modified species to deliver a series of bridged- and spiroacetal derivatives in moderate to good yields. This study represents a new example of nonmetathetic reactions catalyzed by Grubbs-type ruthenium carbene complexes.

  内炔烃的分子内双加氢烷氧基化反应可以使用Grubbs型钌卡宾络合物或其修饰物以中等到良好的产率提供一系列桥缩和螺缩醛衍生物。这项研究代表了由Grubbs型钌卡宾配合物催化的非运动反应的新例子。
